TRAM-RAIL AND CHAIR.

SPECIFICATION forming part of Letters Patent No. 801,317, dated July 1, 188%. Application filed Novembci ld, 1883. (No model.) Patented in England April 17, 1883, No. 1,934,

be used in combination; by which the first cost of production is lessened, the road is improved, the facilities of renewal much increased, dog spikes and bolts rendered unnecessary, and solidity of structure with less vibration of metals and of outside row of stones secured.

According to my invention I roll bar-iron with a groove longitudinally on each side and mid-distance from the top and bottom faces, said grooves having tapered sides. The parts having the top and bottom faces are alike, and enable the rail to be turned end for end and upside down, and firmly secured in the chairs by keys driven partly into the groove on one side and partly into a notch in the check of the chair on that side of the rail. The groove on the other side of the rail receives a feather or wing of the guardrail, the wing forming also the distance-piece, to determine the width of the channel in which the flange of the earwheels can run. The guard-rail is continuous and parallel with the rail proper, and is provided with lips of equal depth, so that it can be turned end for end and upside down,as occasions require, such as when one lip is worn away. The back of the guard-rail is grooved to correspond to a notch in the other check of the chair for the reception of a key which binds the guards-ail in position. The chair or sup port has a rib or a series of projections) in the base of the opening between the two cheeks,on which the feather of the guard-rail rests, and it serves as a support, in conjunction with the key in one check, for sustaining the weight and for preventing oscillation of the rail during the motion of the car. The chair or support has a base or foot, and the checks which form stiffeners thereto terminate level with the top of the rail when fitted in position, and where they serve as stops to any sliding or action of the stones next the rails, and consequent looseness of said stones, which invariably happens, from the fact that the car-traliic on a line of rails always moves in the same direction.

My invention is clearly shown in the annexed drawings. I

Figure l is a side view, and Fig. 2 an end view, and Fig. 3 a plan, of a chair, A, with the rails B Glockcd in position by the keys D E, the'rail G resting on the rib G, as before mentioned.

6 H H are the two cheeks of thechair A, with U notches l; J, for the reception of the keys D E, which also engage into the groove of the rails B and 0, respectively, to hold the rails firmly thereto. It will be seen that the rails at the bottoms are clear of contact with the chair; but a wooden, felt, or other cushion can be arranged therein.

K is the base or foot of the chair, to set on the wood, concrete, or other foundation. The chairs are laid at fixed distances apart and support the rails at intervals; but where a continuous bearing is desired for the rail I shape the ends of timbers to lit onto the ends L L of the chairs, and keep the top surface level with the under side of the rails which rest thereon.

M is the continuous feather of the rail 0, and the edge of it fits into the opposite groove of the rail 13. Its under surface is in direct contact with the rib G of the chair, and serves to resist, in conjunction with the key 1), the downward pressure of passing weights, the head of the rail B, which is undermost, being relieved from compression, and consequent inj ury there from. This feather M determines the distance the two rails B 0 shall be apart, and the space N above it serves as the channel or groove in whielrthe ilange of the car-wheels shall run. The weight of cartraliic, which tends to centralize itself on the inner tread of the rail, and

the rolling friction of the wheel-flange against the side, coupled with the cutting action of the edge of the wheel-flange into the bottom of the channel, according to present constructions of rails, are very disastrous to the duration or working life of a rail, the channeled part of the rail having no support directly under it to prevent spring or buckling. Now, by my invention these inconveniences and (lllSZLilV2t11- tages are completely overcome, the weight of the car being concentrated and borne by the inner edge, a, of the tread directly on. the,

feather located upon the'lip G of the chair A, greatsolidity and stiffness is produced, the rolling friction against the side I) is reduced, and the bottom 0 of the channel N the better able to resist the cutting action of the edge of the wheel-flanges.

Other advantages are derived by the use of this invention. The rail has four working or tread surfaces, and it is readily removed by driving out the two keys D E, to enable any tread to be utilized. The rail 0 can be turned over on end when one side, 0, of the feather M is worn, the whole being as readily replaced and locked in position without delaying or interfering with ordinary traffic.

I claim as my invention- 7 1. The combination of the chair, the supporting-rib, the rail provided with the distancing-feather resting on the supporting-rib, and the rail provided with the groove into which said feather fits, substantially as de scribed.

2. The combination of the chair, the rail provided with grooves on opposite sides, the key supported in the chair and entering one porting-rib, the rail provided with the feather ,0

and the groove, and resting on the saidrib, the key entering the groove of said rail, and a grooved rail to receive the said feather, sub stantially as described.

4. The combination of the chair, the rail 35 provided with grooves in opposite sides, the rail provided with a groove in one side, and a feather on the opposite side entering the groove in the adjacent rail, and the keys fitting into the grooves in the outer sides of the 0 two rails, substantially as described. I

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
